Inspired by the Vocaloid thread, an old idea sprung back to mind;
retro "chip style" speech synthesis.
Is there a simple, minimalistic, Free/Open Source phoneme-to-audio
synthesiser out there? I'm not terribly interested in the
text-to-phonemes part and other higher level stuff, as I intend to
use this for sound effects in games and (other) toys. Doesn't hurt if
CPU and memory requirements are very low, but I'm probably going to
render words and phrases off-line anyway (at install or load time),
for later processing as normal sound effects.

There is the venerable rsynth proggie. It's really old but it's fun
to put the ouput through filters and stuff..
Stil though, it talks very strange...
There is also a smaller/reduced version of festival you can try out,
but i forgot how it is called.

Actually, I was surfing around, looking for that a moment ago. Can't
seem to find any source code, though. (Didn't really expect to.) Is
it available?

Yeah, that's another though... I guess one way would be to replace the
synthesis stage of some current TTS system with a chip emulator style
synth. Or how about hacking a LADSPA or JACK wrapper that generates
control output that you can use to drive a modular synth?

You can do fun things with formant filters (vowel peaks - theres a dial
that goes from A to EE) and envelope sequencers.
If there isn't a formant filter for LADSPA allready available someone
should make one - the tables of co-efficients are available online.

was a LADSPA plugin, though.
Anyway, formant filters might actually be a bit too sophisticated for
what I want to do. I'd prefer something more similar to speech
synthesis on old hybrid sound chips, like the 6581; that is, PWM, S&H
noise and possibly a simple resonant filter.
I've played some with *really* simple stuff, doing PWM on the PC
speaker, and it's not too bad. "Colored" noise for the plosives is
easy (PWM with random phase), and you can get a few vowels from just
pure PWM. Adding an LPF, or alternative waveforms might do the trick.
(A bit tricky to do with the PC speaker, of course, so I didn't try
it back then. ;-)

I looked pretty carefully at the docs and schematics back when I was
hacking on the Amiga, and I never saw anything but the Paula chip (4
simple hardware DAC voices) when it comes to audio. I'm quite sure
narrator.device used only the standard audio output driver.

Here's a link to S.A.M (don't know what the diskette contains):

Funny. Very small. C. Seems to be 100% public domain. Might work. :-)

Looked at that, but it's still too big and too "serious" for my needs.

Well, it's not open, or free, but it's damn impressive:
